Which of the following statements is true?
a. to lose weight, you must consume fewer calories than energy expended.
b. it is considered safe to lose 10 pounds a week.
c. you must exercise at least one hour a day to lose weight.
d. cycling and swimming are examples of resistance training.

The correct answer is A. If you burn more calories than you intake, you body will burn fat to make up for the difference. B is incorrect because losing that much weight that quickly is dangerous. It is recommended you lose 1 pound per week. C is not really true, yes you will burn calories by exercising but you could still be eating too much. D is incorrect because swimming and cycling are low impact cardio. Resistance training applies to weights.

Answer is A.
It is NOT considered safe to lose 10 pounds in one week. You do not have to exercise at least one hour a day to lose weight. You can exercise and not lose any weight, depending on your eating habits. Cycling and swimming are not examples of resistance training. Weights are required for any type of resistance training.
